There are about 9403 clinical studies being (or have been) conducted in Switzerland. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This is a prospective, single-center, observational study designed to to quantify complications following major visceral surgery major visceral surgery (such as pancreatic resection or colorectal colorectal surgery), and to identify digital biomarkers (collected pre, and post-operatively by a connected watch) enabling early early identification of patients with post-operative complications. Patients will be invited to wear a watch during the perioperative period, and will receive questionnaires about their their health status.
The objective of this prospective, international cohort is to incorporate the low stable pressure (using Airseal Insufflator) approach and its associated parameters into the early rehabilitation program after colorectal surgery so as to shorten hospitalization up to the ambulatory care and reduce postoperative pain and opioid consumption.
The Physiological Study of Haemodynamic and Microcirculatory Evolution before/after Transcatheter Aortic Valve Replacement (TAVI) aims to investigate the physiological changes induced by the implantation of a prosthetic aortic valve on blood vessels in patients with severe aortic stenosis. The hypothesis of the study is that adaptive microcirculatory phenomena occur during TAVI implantation. The results of preoperative assessment of microcirculatory functional reserve differ according to whether or not organ dysfunction occurs after TAVI. There is a progressive adaptation of the microcirculation to the new cardiovascular load conditions after TAVI. Early features of this adaptation are associated with the occurrence of short- and medium-term complications.
Hypoglossal nerve stimulation (HNS) plays an increasingly important role in managing patients with obstructive sleep apnea (OSA) who do not tolerate CPAP therapy and are not eligible for other alternative treatment options, such as mandibular advancement devices or positional therapy. The posterior upper airway space dimensions are crucial in managing patients with HNS in the patient selection process and therapy control. The lateral collapse of the upper airway is of crucial importance. Lateral collapse at the palatal level and of the oropharyngeal walls is a well-established negative predictive factor for therapeutic success. Patients with complete concentric collapse at the palatal level (pCCC) in drug-induced sedation endoscopy (DISE) must be excluded from the implantation of HNS, which is cumbersome and invasive. Endoscopy has the inherent limitation that only one level can be observed at a given time, and assessment is possibly hampered by phlegm. During activation and titration of HNS, tongue protrusion is observed in the awake patient. However, this method does not allow for assessing the opening of the retroglossal (RG) and retropalatal (RP) airway space, which is the ultimate therapeutic goal. Insufficient opening of the airway is the reason for non-responders with HNS. Insufficient upper airway opening can be either at the retropalatal or retroglossal level. The study aims to identify insufficient airway openings better using sub-mental ultrasonography. Sub-mental standardized and orientated ultrasonography offers a quantitative, reproducible way of assessing transverse upper airway dimensions and anatomic features of the upper airway in a rapid and non-invasive manner. In addition, anatomic characteristics of the airway's adjacent tissue, such as the size and shape of the tongue, may also have an impact on the effectiveness of HNS. Tongue morphology and posterior airway space assessment could be used in preoperative evaluation and during therapeutic titration of HNS. The clinical routine could be included tongue morphology and posterior airway space assessment without additional patient risks. However, the clinical value of assessing posterior airway space and tongue morphology in patients with HNS is yet unknown.
The primary aim of this study is to investigate the nasal environment in obese and lean individuals.
A retro-prospective case-control Swiss study was conducted to evaluate the diagnostic performance of measuring an antibody index (AI) for intrathecal synthesis of specific anti-Treponema pallidum (T. pallidum) IgG for the diagnosis of neurosyphilis.
Primary aims of the study are to evaluate the feasibility of Skin conductance (SC) measurements and its correlation to Neonatal Pain and Distress Scale (N-PASS) - scores during the Less-Invasive-Surfactant-Administration (LISA)-procedure in preterm infants. Secondary aims are to evaluate the effect of LISA on the general stress-level in preterm infants with respiratory distress syndrome. The assessment of pain and stress with SC measurement in addition to the subjective assessment with N-PASS may provide more conclusive data on the sensation of pain or stress during the LISA procedure and therefore the necessity of analgosedation. Therefore, this study might help to identify those infants in need for analgosedation, which would allow an individualized approach in the future.
This study aims to investigate the effectiveness and safety of implementing a personalized positive end-expiratory pressure (PEEP) management strategy guided by esophageal pressure (Pes), as well as its potential to reduce the occurrence of postoperative pulmonary complications (PPCs) in elderly patients undergoing laparoscopic surgery.
The goal of this clinical study is to test feasibility of a motor-cognitive training program in patients after mild to severe traumatic brain injury in an acute hospitalization setting. The intervention is a step-based dual-task training, i.e. patients are presented with step patterns that they have to memorize and then execute in the tempo given by a metronome. Researchers will assess the feasibility of the motor-cognitive training regarding acceptance and safety, user evaluation of the training and training performance.
There is no consensus on the optimal treatment of patients with high-grade glioma, especially when patients have limited functioning performance at presentation (KPS ≤70). Therefore, there are varied practice patterns around pursuing biopsy, resection, or palliation (best supportive care). This study aims to characterize the impact of palliative care versus biopsy versus resection on survival and quality of life in these patients. Also, it will aim to determine if there is a subset of patients that benefit the most from resection or biopsy, for which outcome, and how they could be identified preoperatively. This study is an international, multicenter, prospective, 3-arm cohort study of observational nature. Consecutive HGG patients will be treated with palliative care, biopsy, or resection at a 1:3:3 ratio. Primary endpoints are: 1) overall survival, and 2) quality of life at 6 weeks, 3 months and 6 months after initial presentation based on the EQ-5D, EORTC QLQ C30 and EORTC BN 20 questionnaires. Total duration of the study is 5 years. Patient inclusion is 4 years, follow-up is 1 year.
